Abstract

The analysis of loss on ignition (LOI) is widely used in paleolimnological reconstructions to understand the conditions of sedimentation and to identify the input of organic matter from external sources as well as pollution in lakes. For the first time in Russia, the influence of organic matter content on Cladocera distribution in five columns of lake bottom sediments in the Kola-Karelian region was analyzed. Using linear regression in the PAST program, it was found that Biapertura affinis, Alona quadrangularis and Camptocercus rectirostris increase in abundance with rising organic matter content, whereas Chydorus cf. sphaericus <and Bosmina (Eubosmina) cf. longispina thrive in conditions of low organic matter content.
